G'day, Rusty here. Alright, let's have a look at what Jaconé has in store for us over the coming weeks. The pattern is a bit of a mixed bag, with some promising windows of clean surf, but we’ve got a stretch of rough, onshore junk to get through first.
Right off the bat, Sunday the 12th isn't a total loss. We've got a small, clean 3ft groundswell from the SE, with a 12-second period and a light cross-offshore breeze. The wave energy is moderate (286), and conditions look fun for an intermediate surfer, just keep in mind this break can get crowded sometimes. The water temperature is about average for this time of year.
However, the fun stops quickly. Sunday afternoon turns onshore and messy, and Monday the 13th is a write-off – we're looking at a solid 8ft of wind-affected, onshore slop with strong, onshore winds. Wave energy builds to a massive 1243, but it's completely unsurfable. That onshore wind and rain continues into Tuesday, with the swell still over 7ft and the energy at 1098. Tuesday afternoon is only marginally better, still rough with a strong cross-onshore wind.
Wednesday the 15th morning is where it finally turns the corner. The sky clears, and we get a clean 7ft SE groundswell (11-second period) with light offshore winds. Wave energy is moderate (963). For an intermediate surfer, this is the first real standout of the period – clean, offshore, and a proper size. Thursday the 16th morning is also very good, with 6ft SE swell and light offshore breezes.
After that, the surf drops back in size but stays clean through the end of next week and into the following week, with smaller 3ft to 6ft waves and mostly light offshore or cross-offshore winds. It's consistent and clean, perfect for logging some easy miles.
Then we get a real standout on Saturday the 26th of July. Sunday morning, we've got a beautiful 6ft SSW groundswell, 12-second period, and glassy conditions with barely any wind. Wave energy is very strong at 1469. This is a long-period groundswell, so it's better suited for a point or reef, but the conditions are described as excellent for experienced surfers. At over 5ft, it’s pushing it for beginners, but for the experienced crew, this looks like the pick of the whole run. Monday the 27th morning keeps the trend going with 5ft of S swell and glassy conditions.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
